APPARATUS HAVING STOP-MOTIONS.

Specification of Letters Patent.

Patented Sept. 24, 19o7.

Application filed as as, 1906. Serial No. 323,010.

ToaZZ whom it may concern:

Be it known that I, HARRY A. HASELDEN, a citizen of the United States, residing at Whitinsville, in the county of Worcester and State of Massachusetts, have invented certain new and useful Improvements in Apparatus Having Stop-Motions, of which the following, taken in conjunction with the accompanying drawings, is a full and true Specification.

This invention relates to the stop motions of certain combined apparatus, such as cotton combing apparatus, wherein one part, such as the draw-head thereof delivers a continuous supply of sliver, and another part, such as the coiler, receives and operates upon said supply, and the invention consists in the provision of means whereby the operator can temporarily render said stop motion inoperative on specialoccasions, as for example, when the sliver issuing from the draw head has broken down and the sliver detector of the coiler apparatus has brought about a stoppage of the machine, so that the operation of the machine may be continued while he repairs the sliver by splicing the broken ends, or otherwise restores the machine to its fully operative condition.

In the accompanying drawings, Figure 1 is an end elevation of a part of a cotton combing machine showing the delivering rolls thereof in elevation and the coiler apparatus in vertical section, and also showing the stop motion apparatus and circuit partly in diagram; Fig. 2 is a top plan view of Fig. I with parts shown in dotted lines and parts broken away; Fig. 3 is an enlarged side elevation of the circuit breaker with the insulation in section, and Fig. 4 is a top plan of Fig. 3.

In Figs. 1 and 2, A represents the end standard of a cotton combing or other similar machine adapted to' deliver its work, such as combed sliver in continuous form, and 13 represents the delivery rolls of the drawhead of said machine. The coiler apparatus is located adjacent the delivery rolls and is adapted to receive the supply of sliver therefrom and coil it within the can O. The coiler apparatus is of usual construction and comprises an upright hollow frame-post D, at itsupper end supporting the coiler head, which latter comprises a top plate D within which the horizontal coiler gear D is mounted, said gear being provided with the usual inclined sliver conduit D and being peripherally supported upon an annular flange in the said plate wherein it is driven by a pinion E on the vertical coiler shaft 13 which latter is driven by the beveled pinions E from the combing machine or other source of power. The coiler gear bonnet Fcarries the journals of the calender rolls G, which are located directly over the upper end of the sliver conduit D and geared together by the gears G so as to be driven in unison through the beveled pinions E by the afore- .arm of lever H mentioned shaft E (see Fig. 2). The trumpet cover I H surmounts the coiler gear bonnet and carries the trumpet H above the calender rolls and also the pivoted sliver detector H The cover H is pivoted to the casing or frame-post D at the point H and the bonnet Fig. 1, emerges from the rolls B and passes over the sliver guide H and over the fork or spoon of the detector lever H holding the same in the position indicated, and from thence the sliver passes through the trumpet and calender rolls into the sliver conduit D of the coiler gear by which means it is coiled in the can.

The sliver detector has an arm within the cover H provided with a counter-balance which is so adjusted that in the normal working of the apparatus the weight or draft of the sliver on the spoonof the detector will maintain the said arm elevated, but when said sliver breaks down or fails for any reason, the said arm falls to its operative position in which it brings about the actuation of the stop motion, causing an automatic stoppage of the machine and thereby preventing waste of material.

In the case under consideration, the stop motion comprises an electrical circuit and apparatus which, being of usual construction, is herein shown in diagram.

Referring to Fig. 1, the stop motion comprises a source of electric current K with one pole connected to the metallic frame of the machine and the other with one of the poles of a suitable electrical knock-off device L, which when energized shifts the driving belt of the machine or in some other way interrupts the supply and lowframepost D, and from thence by wire K to an insulated terminal spring 0, which has separable contact with the hooked spring of the insulated detector contact P, the latter being carried by parts fixed to the removable bonnet F and directly beneath the weighted In this position the said lever is device remains energized the machine cannot be re- 1O5 started. I

The circuit breaker M, above mentioned, comprises two spring leaves 1 and 2, respectively secured to opposite sides of a block of insulation 5 which is bolted to the side of the frame post D. The free ends of the two springs are in mutual, spring-pressed contact and an aperture is provided in-the lower leaf to receive the boss of a thimble 4 of insulating material which is inserted between the two springs. The upright rod 5, mounted for reciprocation in the brackets 6 within the frame post, fits with its upper end in a socket in the said thimble and at its lower end is stepped upon the end of a pivoted foot treadle 7 or other part extending to the outside of the coiler post, whereby the operator can move the rod a suflicient distance to spread apart the spring leaves and open the circuit. The elasticity of the upper spring leaf or the weight of the rod or connected parts, or both, tend to return the leaves to their normal closed position.

In order for the operator to piece broken ends or reinsert the sliver between the rolls G, when the machine has been automatically stopped by the action of the detector he must first start the machine and keep it in motion until it has delivered a sufficient length of sliver for this purpose. By operating the rod 5 he is enabled to open the circuit and hold the stop motion temporarily inoperative during this interval, so that after having started the machine by pulling the starting handle B, (Fig. 1) the machine will proceed to deliver sliver notwithstanding the fact that the detector is momentarily in its circuit closing position.

By locating the circuit breaker at the upper end of its actuating rod and the treadle 7 near the base of the coiler, the operator may operate the circuit breaker with his foot and enjoy the use of both hands in piecing,

' and upon the withdrawal of his foot, after the sliver has been restored, the circuit breaker returns to its normal condition by virtue of its spring or gravity, whereupon the stop motion is again fully operative for protecting the machine.

The invention is not confined to the specific form of detector mechanism asherein illustrated nor to the special agency by which the stoppage of the apparatus is brought about. Other-and additional detector apparatus may also be employed if desired and other forms of circuit breakers will be equally as serviceable as that shown herein provided they are returned to normal position by spring or gravity.

In Fig. l the coiler gear bonnet is provided with an additional contact terminal S connected with the contact terminal P by means of the wire S and located just above the rim of the coiler gear D The stop motion circuit is closed at this point when the coiled sliver in the can C rises to such an extent that, crowding under the coiler gear, it raises it into contact with the end of the terminal S thereby stopping the machine until the full can is removed and another inserted in its place; but if desired the full can may be removed without stopping the machine by holding the treadle down while the cotton is crowding under the coilergear.

Having described my invention what I claim and desire to secure by United States Letters Patent is the following:

1. The combination of a lnachine adapted to deliver its work in continuous form, an apparatus supplied by said machine having a detector adapted to cause the stoppagli of said machine upon the failure of the supplied work, a device functioned to render said detector inoperative and adapted to be held and maintained in its effective position for this purpose by the operator, and means tending to restore said device when released by the operator.

2. The combination of a sliver delivering machine. means for starting the machine, a stop motion circuit, an apparatus supplied by said machine having a sliver de tector controlling said circuit, and an automaticallyreturned circuit'breaker for said circuit adapted to he held by the operator in the position in which the said circuit permits the re-starting of the machine.

3. In apparatus of the kind described, a sliver-dc]ivering machine, and a coiler supplied thereby having an upright frame post, in combination with a stop motion apparatus adapted to cause the stoppage of the machine upon the failure of the sliver and means located near the base or the frame post for temporarily rendering said stop motion apparatus inoperative.

-i. In apparatus of the kind described, a coiler head. :1 supporting post therefor and a detector on said head. in combination with an upright movable rod supported by said post and means at the upper end of said rod, adapted for actuation thereby, to render said detector inoperative.

5. In apparatus of the kind described. a coiler having a hollow frame post and a detector, in combination with a stop motion circuit controlled by said detector, a circuit breaker in said circuit mounted within said hollow frame post, and means extending to the outside of the post whereby the operator may operate said circuit-breaker to render said circuit temporarily inoperative.

In testimony whereof, I have signed my name to the specification in the presence of two subscribing witnesses.
